Introduced in 2008 by a programmer or group of programmers using the pseudonym Satoshi Nakamoto, the Bitcoin was the first of its kind, turning the science fiction fantasy of a decentralized, encryption-based global currency into reality.

Despite recent largely overstated and misinformed controversy over illegal uses of the Bitcoin, the cryptocurrency is the foundation of a generally credible and secure global digital payment network. While other cryptocurrencies have since emerged, Bitcoin remains the most prominent with a market value of over $10B USD. Blockchain estimates Bitcoin has roughly 1.2 million users, working out to an average wallet value of around $10,000 USD.

But Apple doesn't want its iPhone customers to be able to use their Bitcoin assets on its devices.

In recent months it had already purged Coinbase and CoinJar, two similar apps that acted as trading portals and wallet apps for the Bitcoin. CoinJar blogged about the rejection, but was measured, saying it contacted Apple and was told that Apple didn't generally allow Bitcoin apps. CoinJar suggested this might be because of the uncertain global legal status of the Bitcoin.

But Blockchain believes Apple may have a darker anticompetitive purpose for its transactions. In a blog Blockchain comments:

These actions by Apple once again demonstrate the anticompetitive and capricious nature of the App Store policies that are clearly focused on preserving Apple’s monopoly on payments rather than based on any consideration of the needs and desires of their users.

In comments toWired, Blockchain CEO Nicolas Cary said that he believed the undisclosed reason for these terminations of popular apps was because Apple is plotting to release a digital payments app for iOS. Such an app -- similar to Google Inc.'s (GOOG) current "Wallet" app -- would compete with Bitcoin as a secure digital payment mechanism.
